Patented June 21, 1932 UNITED STATES "PATENT err esp i HERMAN LE QUORNIK, OF RICHMOND HILL, AND DOMINICK SALVATI, OF BROOKLYN, NEW YORK, ASSIGNORS, BY DIRECT AND MESNE ASSIGNMENTS, TO EASY-DRIVE GARAGE CORP., OF BROOKLYN, NEW YORK, CORPORATION OF NEW YORK FLOOR CONSTRUCTION Application filed August 27, 1929. Serial No. 388,661.

The invention resides in a special construction of buildings containing more than one story whereby a continuous floor is formed from the street level to the top story. The main object of the invention is to so construct the floor that its ascent from story to story will be at a constant and very easy pitch. Another object is to so construct the floor that more available floor space is obtained than would be the case in a building of the same size having separate floors for each story. A further object is to so con struct the floor that it will deduct from rather than add to the cost of the building.

These and other objects and advantages will be clearly understood from the following description and from the accompanying drawing, wherein Fig. 1 is a perspective elevation having certain parts broken away to show the interior, and

Fig. 2 is a plan view.

The building shown in Fig. 1 has a part of its front and side broken away and its roof removed. The ascent of the floor 10 starts immediately inside the entrance 11 and continues with a gradual pitch to the story above where it is shown broken at 12 and the floor of the intermediate stories omitted. The floor is supported by the walls 13 and by a plurality of columns 14. This construction continues right to the top story. In the upper story the floor is shown broken at 15.

As the flooring occupying the spaces 16 and 17 between the columns 14 is practically level, openings 18, 19 and 20 are formed. In practice these openings are bricked up or otherwise closed or guarded. It will be understood that, while we have shown the floor as it would appear if constructed of concrete, any suitable material may be employed in the construction. In buildings having a large area, additional columns may be placed between the walls and the columns 14.

By referring to Fig. 1 it will be noted that the openings 18, 19 and 20 are vertical and that, as shown in Fig. 2, no floor space is lost by forming these openings. They are, when viewed as in Fig. 2, what may be termed slits forming a Z; the ends and corners of the slits being supported by thecolumns 14.

1. A floor construction consisting of a continuous helical floor ascending from the lowest to the highest story of a building and supported by the outer walls and a plurality of central columns, the floor space of each convolution being substantially coextensive with the plan of the building and consisting of portions at different levels separated along straight lines;

2. A floor construction consisting of a continuous helicalfloor ascending from the lowest to a higher story of a building and supported by the outer walls and a plurality of central columns, the floor space of each convolution being substantially coextensive with the plan of the building and consisting of portions at difierent levels separated along straight lines which do not reduce the floor area.

3. A floor construction consisting of a continuous helical floor ascending from the lowest to a higher story of a building and supported by the outer walls and a plurality of central columns, the floor space of each convolution being substantially coextensive with the plan of the building and consisting of portions at different levels separated along straight lines located between a plurality of the central columns. 4
